I looked over the website for this product, and, having tried other gutter guard products, all with limited success, I decided to give it a try. One thing I did NOT notice was a small caveat buried in the installation "warnings"- if you have a metal roof, you "have" to have something called "ice cleats". In my area (Atl metro) it would be very hard to find someone who even knows what those are. In any event, they would not have helped in this case. After a heavy snow, I noticed that as the snow was thawing on the roof, and re-freezing, it was "grabbing" the material of the Flo-Free and pulling it out of the gutter. This was kind of a last straw, since prior to this, I was cleaning debris off the lip created by the way it is installed, on a monthly basis. I had actually recommended this product to some clients of mine, but now am sorry I did. Now I am out not only the cost of the material, but the labor, as well. Despite the fact that ice cleats would not have helped in this case, the company's position is that they are not liable, since I did not have them installed. I am very disappointed in the product, and would heartily recommend against it.

You could try VersaScreen Gutter Protection. It can be installed with metal roofing and will not be pulled out when the snow slides off the roof. In areas where ice dams are a problem it can also be installed with an integrated heat cable system. www.VersaScreenGutterProtection.com
